Raw, smoked, pickled, roasted or grilled — there are so many wonderful ways to prepare mackerel. Smoking is particularly fantastic, because it really holds in the flavour. Once, on a cooking job in Scotland, we were presented with lots of mackerel someone had just caught. We filleted and thinly sliced the fish and served it as sashimi with dipping sauces. It was the freshest mackerel we’d ever tasted.
